ernor mechanism without prcckct-whcel 17, which is adapted to be .llifiYll into or out of operation, to govern ihc actuation of the moving picture machine by the motor drive, by means of suitable ontrolling mechanism. The preferred conlllCtlOll for the latter purpose comprises a rod, 19, extending longitudinally of the shaft 9 and slid-ably mounted in a. longitudinal bore therein, which rod carries at one projecting end a ratchet disk, 20, adapted to engage a corresponding ratchet, 21, upon the sprocket-wheel 17. The rod 19 is locked in engagement with the shaft 9, for rotary action therewith, by means of a cross-pin, projecting in an elongated slot, 23, in

actuating the the shaft 9 which permits the slidable action of sai rod. The rod 19 thus revolves with the shaft 9 and carries the ratchet disk 20, and when said rod is moved to bring the disk 20 in engagement with the ratchet of the sprocket-wheel 17 the latter is carried with the shaft 9 and operation communi rated to the moving picture machine. Said rod is normally controlled, by a suitablymounted sprin 24, to retain the ratchets 70 and 21 in engagement, and to lock said rod against this spring control, and with the ratchets 20 and 21 disengaged, a pin, 25, is slidably and turnably mounted in an extension, 26, from the casing 5 and bears against the end of said rod. Said pin 25 has a milled head, 27, by which it may be .opcrated, and carriesa laterally-projecting pin, 28, having a locking action in a right an lar slot, 29, in the extension 26.

pon the shaft 9, adjacent the block 12, provided a fixed collar or projection, 30, acting as a stop for the slidable action of said block in the movement of the disk 14 away from the disk 7. The operative action ct this stop 30, in the operation of the governor mechanism, is such that when the speed results in movement of the disk 14 from frictional engagement with the disk 1' the block 12 impacts against'the stop and the latter acts under the impact to throw the disk 14 back in its movement for frictional reengagement with the disk 7. ll 'he action of the governor mechanism is thus such that the frictional engagement of the disk 14 is intermittent, its movement bekg' intermittently to and from frictional mtact with the disk 7, whereby the revoluons of the disk 14 and its shaft 9 are conrrently less than the revolutions of the i 7 and its sleeve 6.

To effect adjustment of the governor meclmnisn] with relation to the speed of the theft 9, the relative normal positions of the slidable blocks 11 and 12, and the tensional status of the springs 15 resulting therefrom, is adjustable. The preferred construction for this purpose comprises a rod, 31, having a threaded mounting, as at 32, whereby it may be turnably held in position, and car rying a circumferentially-grooved collar, 33, the grooveof which receives the free end of an arm, 34, pivotally mounted, at 35, and engaging, beyond its pivot, a circumferential groove, 36, in the block 1-1. The arm 34 thus constitutes a lever, adjustable by turning of the rod 31 and held in fixed adjusted position thereby, and acting to retain the block 11 at a normal relative adjusted position. The rod 31 extends beyond the casin 5 and is provided at its end with a milled head, 37, by which it may be operated. In the operative status of the mechanism, the rod 31 is primarily adjusted to effect the desired adjustment of the gov ernor mechanism with relation to the normal conditions of speed required for synchronized movement, and to govern fast or slow conditions which may exist under this primary status of adjustment, in the circumstances of synchronized operative action be tween the moving picture machine and the talking machine, a supplementary adjust ment means is provided for employment while the mechanism is in operation. The preferred construction for the latter purpo'se comprises two ratchet disks, 38-38, carried by the rod 31 and having reverse ratchets, as shown in Fig. 7. and between these disks is mounted an arm, 39, free upon the rod 31 and turuahlc thereon and having an operating handle, 40. Said arm 39 car ries, respectively at opposite sides, two reversely-mounted gravity or spring-actuated pawls, 41-i1, adapted for convenient finger manipulation for disengagement from the ratchets and respectively engaging the reverse ratchcts 38. Said arm 3.) also carries a pointer, as at 42, projecting with relation to a guide point or scale, as at 43, upon a suitably mounted plate, 44. In the primary adjustment of the rod 31, by means of its milled head 37, the pointer 42 is set at the guide point 43, which is the center of the guide or scale, this positioning of the arm 39 and its pointer 42 being conveniently permitted by manipulating the pawls 41 to permit movement of the arm 39 without turning the ratchets 38. The adjustment of the governor mechanism is then in normal position for operation, but when it is desired to run fast or slow, according to any conditions of the synchronized operation of the moving picture machine and talking machine, the arm 39 is moved in one direction for faster adjustment and in the other direction for slower adjustment, during which movement one of the pawls 41 will engage and turn one of the ratchcts-3S while the other pawl is held disengaged, and the turning of the ratchet will correspcndingly turn the rod 31 for adjust mcnt. Normally, the pawls 41 operate to lock the arm 39 in its adjusted position. A spring- 111 the g:

The contacts 62 and 63 of the commutator are comprised in an electrical circuit in which is arranged an electro-magnet, 64, by which the indicator mechanism is operated. Said magnet and indicator mechanism is arranged adjacent the moving picture machine, and is preferably mounted upon the casing 5 of the governor mechanism of the picture machine, as shown in Fig. 5, and it may be inclosed in a suitable supplementary casing, as shown at 65, in Fig. 1. A preferred arrangement of the indicator circuit is shown in Fig 2, in which a conductor, 66, extends from the commutator contact (32 through a resistance coil, 67, to the electro magnet 34, and from the magnet a conductor, 68, extends through a battery, 69, to the commutator contact 63. A suitable switch as at 70, is preferably arranged in this circuit, by which it may be thrown into and out of operation as desired.

The indicator mechanism comprises a suitable framework, 71, in which is mounted a shaft. 72. the forw (l portion of which is preferably reduced. at 73. to form a thrust bearing. 74. said shaft being adjustable to its bearing 74 by a suitable set-screw bearing, as at T5. The shaft 72 carries two spaced disks, 76---76, which have a circular ratchet-edge at their respective inner faces. as at 77, which ratchets are relatively reversed so that they operate in reverse directions while the disks 76 are carried by the shaft 72 in the same direction. The armature, 78, of the magnet 64. is carried by an arm. '79, pivotally mounted beneath said armature. as at 80. and projecting at the side of the ratchet-disks T6. Said arm i controlled in its return movement by a' spring, 81. and is provided at its "free cut with a pin, 89, projecting. betmeen the ratchet-disks 7G and operating with relation to the ratchets T7. As said arm 79 oscillates. under alternate action of the armature TR and the spring 81. its pin 82 bears first with relation to one ratchet 77 and then with relation to the other ratchet 77 and by pressure upon the inclined faces of said reversed ratchets 77 causes the rotation of the shaft 72 in successive steps corresponding to the makes and breaks of the armature 78. The shaft 72 carries at its forward end a suitable pointer, 83, secured in connection with the shaft in any suitable manner. Upon the reduced port ion 73 of the shaft 79 is revolubly mounted a sleeve, 84, carrying at its forward end ascal -platc, underlying the pointer 83 so that th latter projects with relation to the scale-points upon the plate 83. .aid scale-platc preferably mount:

ed in connection with the end of the sleeve l i l 84 by a friction socket. as at: 86. and proided with a projecting arm, 87, having a finger hold. 89, by manipulation of which said plate may he turned upon its socket connection with the sleeve 94 to adjust its relative position under conditions or circumstances as may be required or desired. The sleeve 84 is actuated. to revolve in the same direction as the shaft 72, by connection with the moving picture machine, and in the preferred construction for this purpose a sprocketavheel, 89, is carried by said-sleeve and is in connection with the operating iechanism 0f the picture machine by a sprocket chain, 90. The relative adjustment of the actuating means for the sleeve 84, with relation to the normal conditions of synchronized operation of the moving picture machine and talking machine, is such that the scale-plate 85 and the pointer will normally move at the same rate of spool and in the same direction. and any variation in this normal status will be indicated by the pcsition of the scale with relation to the pointer 83. showing that the moving picture machine is fast or slow with respectto its synchronized relationship to the speed of the talking machine, which variable conditions are compensated for by adjustment of the governor mechanism of the picture machine. through the secondary adjustment means hereinbefore de cribed, until the scale-plate 85 and the pointer 8 egister a. normal relative status. The ii .iior mecnanisnr thus shows at all times the relative speed conditions between. the picture machine and talking machine and any variaticn thereof and the adjustment of the governor mechanism with reference to the status shown by the indicator mechanism provides for any desired regulation of the synchronized status under all conditions of opera- .i'iou and use. A spring pressuiebrake, 91, hearing with relation to a suitable collar, 92. secured upon the sleeve 84. is preferably provided to enhance the uniform action of said sleeve.

The circuit of the motor drive 50 for the talking ma hine is shown at 93 and the circuit of the motor drive 2 for the moving picture machine is shown at 94, Fig. 2, and each of these circuits is preferably provided with a switch, as at 95, whereby they may be independently thrown into and out of operation as desired under any conditions or circumstances of use. These circuits 93 and 94 are broken at a switch mechanism. whereby both circuits may be simultaneously thrown into operation, to cause and maintain the relative operation of the moving picture machine and talking machine and the indicator mechanism. or thrown put of operation to cause the simultauetuis sto 'ipage if all of said parts of the apparatus.

Said bellcrank lever 128 is controlled by a spring, as at 131, and the action of the mechanism just described is therefore such that the chain 18 is kept taut by the guide pulleys 126, under movement of the bell-crank lever 128 and tension of the spring 131, in the variable positions of the slidable frame-up mechanism 124 of the picture machine. The sprocket chain 90 has a corresponding takeup means, which is reversely arranged with respect to the take-up means for the chain 18, said chain 90 passing from the sprocketwheel, 132, of the operating mechanism of the picture machine, over guide pulleys, 133l33, carried upon arms, 134134, of a bell-crank lever, 135, which is spring-controlled, as at 136, and mounted upon the sleeve 84 of the indicator mechanism.

Under some conditions of use, especially where the employment of the crank mechanism in connection with the moving picture machine is required, the crank mechanism as abovedescribed and the switch mechanism which it controls and the spring con 5 tact means 96 in the talking machine and l picture machine circuits may be dispensed l with, and said circuits can be opened or; closed simultaneously by an ordinary switch. L simple arrangement for the purpose just indicated is shown in Fig. 2, in Whichl branch wires, as at 137 and 138, extend] from the respective-sides of the talking ma chine circuit, and branch wires, as at 139 and 140, extend from the respective sides of the picture machine circuit, said Wires being assembled at terminals convenient to the picture machine and adapted to be operated by a suitable snap switch, 141, by operation of which the talking machine and picture machine circuits can be opened and closed. A corresponding arrangement of branch wires may extend from the picture and talking machine circuits to terminals and a switch located convenient to the talking machine, if desired, whereby the circuits may be correspondingly controlled I from the talking machine, as will be readily l l understood. I aYso prefer to carry branch 1 wires. as at 142 and 143, from the talking machine circuit 93 to terminals and a switch, 144, convenient to the picture machine, whereby the talking machine circuit can be controlled from the picture machine, i to start or stop the talking machine under 1 circumstances or conditions which may make this action desirable. A correspondg ing arrangement of branch wires from the picture machine circuit 94 may also extend to terminals and a switch convenient to the talking machine, whereby the control of i the picture machine circuit for starting or stopping may be governed from the talking machine. if desired, as will be readily inn 1 derstood. l

It will be understood that should the conditions of synchronizing require increase in the speed of the picture machine beyond that effected by its motor drive, the picture machine could be speeded up by action of the crank mechanism; and that the connection of the crank mechanism with the switch 9697 could be dispensed with, and the motor drives of the picture machine and talking machine circuits be kept in operation by action of the snap switch 141, under which circumstances the picture machine could be cut out from its motor drive at the ratchets 20 and 21 and run entirely by the crank mechanism, or the picture machine circuit could be opened at its switch 95 without ailecting the operation of the talking ma chine circuit, and under these conditions the synchronizing will be shown by the indi *ating mechanism.

The operation and advantages of my in \cution will be readily understood by those skilled in the art to which it appertains.

in practice, the talking machine is usually mounted in rear of a screen or apron, in suitable position which may be upon the stage of a theater, and the moving picture machine is placed in front of the screen, usually in the balcony of a theater and therefore a considerable distance from the talking machine. The indicator mechanism, and the general controlling means for the synchronized operation, are arranged adjacent to the picture machine, in convenient position for manipulation by the operator of the picture machine. In the initial operative arrangement and adjustment of the apparatus, the governor mechanism for the motor drive of the picture machine is set in its. primary adjustment to cflect the desired normal rate of revolution of the picture machine mechanism (which is normally about nine hundredand sixty revolutions per minute, for the projection'of one picture of the film at each revolution), and the governor mechanism of the talking machine is primarily adjusted to effect the de ired normal rate of revolution of the soundrccord (which is normally about eighty revolutions per minute). The relationship of the relative speeds just indicated is therefore normally such that twelve pictures l are exposed during the period of one revolution of thc sound-record. The relative adjustment of the indicator mechanism is such that thc pointer 83 is advanced one step for each picture exposed, by action of thc connnutator operated by the picture machine 'ucclmuism. there being twrlvc step action through said commutator and indicator mechanism to each revolution of the sound-rccord. and [he scale-plate 95 is ad vanccd one step for each picture exposed. through the action of its operating conucction with the mcchanisln oi thc picture um- .taiking machine and picture 71711111111 3 in primary aajustnunt as fibOVb chine.

When the mechanism is run under the conditions just stated, the motor drive of the picture machine can either continue in "o eration, with disconnection at the .ratchets 20 and 21, or the picture machin circuit may be opened at the switch 95 to discontinue the motor drive in that circuit; or, under some conditions of this character of operation, the motor drive and circuit of the picture machine may be entirely dispensed with. Also, the connection of the crank mechanism with the switch 96-9.7 may be dispensed with, and the picture machine run by the crank mechanism, without any motor drive, and with the talking machine'circuit and its motor drive maintained in operation by closing the switch 144, under which conditions the synchronizing-will be shown by the indicating mechanism.

Having thus described my invention, I claim and desire to secure by Letters Pat.- ent:
